The general equation of a line is:
When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
The height of the water tank is 6.
L x W x H = V (volume)
15 x 10 x 6 = 900 cubic feet
L x W x H = V (volume)
15 x 10 x 6 = 900 cubic feet
Answer:
See below
Step-by-step explanation:
We start by dividing the interval [0,4] into n sub-intervals of length 4/n
Since f is increasing in the interval [0,4], the upper sum is obtained by evaluating f at the right end of each sub-interval multiplied by 4/n.
Geometrically, these are the areas of the rectangles whose height is f evaluated at the right end of the interval and base 4/n (see picture)
but
so the upper sum equals
When both
and
tend to zero and the upper sum tends to
